The circuit uses SK-IV voice-control integrated circuit as the core component. Since the manifold requires three times of sound emitted by user continuously at a specific time to trigger the work, the circuit has a very high anti - interference performance. VS can use the 6V, 1/2W Zener diode; VTH1 , VTH2 should use 1A/400V small plastic Triac with small trigger current, such as MAC94A4 with control load being up to 100W; T is 220V/9V, 5VA small-quality power transformer. Other components have no special requirements.
